Say you're feeling cranky, blue, down, bummed out--or any number of other adjectives to describe your day-from-hell. One of the best ways to improve your mood, remind researchers in a brand new study out this week, is to flip on some music. Seriously, music you love--whether it's Bach or Beyonce--is a true mood-altering substance.

The latest news comes from Australian researchers who found that music had the power to soothe and the stress hormones of terminally ill patients in hospitals. Past studies have linked music with improving happiness, helping babies nurse better and a long list of other impressive benefits. Imagine what it could do for your bad mood?

Do you listen to music while you work? Do you find that it has mood-boosting effects?
